Re: [sumo-user] Disconnect with Traci

[胡志强]

Hi Jakob,
I have add the option numTries=100 to traci.start(),but the error is still
exist.Could you please tell me is there a approach to repeat my simulation
in the same traci ?Then ,I don't need to connect the server again and
again,my problem solved.

Best regards,
Zhiqiang

[胡志强]

Hi Jakob，
Thank you,it works.But the problem is also exist,it retries for 101 times
then closed and I'm sure that my computer's memory is enough.And I also
occurred the error that "connection closed by SUMO",If you want more
details,tell me.

 Hi,
 My SUMO version is 0.32.0,and I write a loop to simulate for many

 for i in range(2):

 At the beginning,it works well,but it may disconnect with traci and the

 Hi Zhiqiang,

 it could be helpful if you provide some more details:
 Under what circumstances does the connection fail? Do the circumstances
 during failure differ from before? Does it disconnect while it is
 connected, or not connect at all? Etc.
 Also, how are you starting SUMO, manually, programmatically? Etc.

Re: [sumo-user] Disconnect with Traci

[Jakob Erdmann]

 - Possibly the simulation cannot start in time because the computer is
still busy from closing the previous simulations. You could add the option
numTries=100 to traci.start() to diagnose this
- Possibly, the simulation cannot start successfully because your computer
is out of memory (which might indicate a memory leak in sumo).

Re: [sumo-user] Disconnect with Traci

[胡志强]

 Hi,
My SUMO version is 0.32.0,and I write a loop to simulate for many times, I
start SUMO like this:
for i in range(2):
traci.start([sumoBinary, "--start","-c", "data/cross.sumocfg",
  "--tripinfo-output", "tripinfo.xml"])
...
...
traci.close()
At the beginning,it works well,but it may disconnect with traci and the
time points is different.I don't know what's wrong.

Re: [sumo-user] Disconnect with Traci

[Menno van der Woude]

Hi Zhiqiang,

it seems like SUMO is not running, since the the client cannot connect 
to the TCP server. Make sure you start SUMO with the --remote-port  
option as described here: http://sumo.dlr.de/wiki/TraCI#SUMO_startup.


If you need to simulate many runs, you will have to automate starting 
SUMO as well.


Greets,

Menno

How can I fix it?
